BOOK-FILLER.

Application filed July 29, 1920.

l '0 all LO/1.0777, it may concern lie it known that I, llocns'ros Ronnn'r Townns, a citizen of the United States, and a resident of Richmond, in the county of l-lenrico and State of Virginia, have invented certain new and useful Improvements in Book-Fillers, of which the following is a specification.

My invention is an improvement in book fillers, and has for its object to provide a book filler having all the advantages of a bound and sewed fiat opening book, with the added features of the loose leaf book, in that the filler may be attached or detached at will from the binder.

In the drawings:

Figure l is a perspective view of a filler in place in a binder.

Fig. 2 is a similar View of the filler and its attaching tapes.

Fig. 3 is a perspective view showing the filler attached to the back.

Fig. 4 is a partial perspective view of the back section.

Fig. 5 is a partial section of the bound book.

Fig. 6 is a perspective view of a portion of the filler showing a modified form of attaching means for attaching the filler to the back section.

In the embodiment of the invention shown in Figs. 1 to e, fillers are provided indicated at 1, consisting of any desired number of leaves, the said leaves being formed by folding the sheets together, and the fillers are sewed to attaching means for attaching them to the back section 2 indicated at l. As for instance tapes 3 may be used, a suitable number of tapes being provided, which are arranged transversely of that edge of the filler which is to be adjacent to the back section of the completed book, and the leaves are sewn to these tapes as indicated at a. By means of the tapes the fillers are attached to the back section 2.

This back section which is of wood or other suitable material is D shaped in cross section in the present instance, although it is obvious that it might have any desired or suitable cross section, that is the filler has one of its opposite faces concaved and the other convened, the other two faces being parallel and plane, and the tapes 3 are folded about the back section as shown in Fig. 8, and the ends of the tapes are con- Specification of Letters Patent.

nected together, in any suitable manner, as for instance by stitching as shown.

The back section 2 is provided near its ends with openings 5 in the present instance, for receiving the posts 6 of detachable covers 7 and 8, each of which has a hinged strip or section 9 and 10 respectively at one edge, the said strips engaging the back section 2, while the bodies of the covers 7 and 8 engage the opposite faces of the filler. It will be obvious that any form of loose leaf back may be used, either that form having posts, or those forms using clamps or other attaching means.

In the embodiment of the invention shown in F 6, the filler 1 is the same as that of Fig. i and Fig. 2, but instead of using the tapes 3 for connecting the filler to the back section 2, a sheet 11 of fabric material, as for instance crash or the like is used, the sections of the filler being sewed to the sheet 11, as indicated at 12. It will be obvious that instead of tapes, cords might be used, or any other means that would be suitable for the purpose.

With the improved fillers, when a filler has been used and is obsolete it may be removed from the binder, by detaching the binder from the back section 2. Now by cutting the tapes or whatever means is used, the filler is detached from the back, and the back section is ready for another filler.

As is known, sewn books have certain advantages over the loose leaf books, in that they can be opened flat, to furnish a flat surface upon which to write. This is not true with the loose leaf binder but because the papers are not hinged as in the sewn book, but are clamped tight together in one edge, thus forming an uneven and very unhandy writing surface when the book is opened. With the present construction however, all the advantages of the flat opening bound book are retained, but in addition there are added the good features of the loose leaf book, in that the leaves of the book are in the form of a filler which can be detached from the binder, thus saving the loose leaf binder. /Vhen the pages of the book become obsolete, the used filler can be transferred to a storage binder, and a new filler inserted into the binder.

I claim: I

l. A book comprising leaves, a flexible element secured to the leaves and extending beyond the same, and a back section embraced by the extended portions of said flexible element.

2. A book comprising leaves, a flexible element secured to the leaves and extending beyond the opposite sides oil the same, a back section extending along one edge of the leaves and embraced by the extending portions of the flexible element, and covers secured to said back section.

3. A book comprising leaves, a flexible element secured to the leaves and extending beyond opposite sides oi the same, a back section embraced by the extended portions of said flexible element, and covers having attaching portions arranged on opposite sides of said back section and securely engaging the extended portions of said flexible element.

4. A book comprising leaves a flexible element secured to the leaves and extending beyond opposite sides of the same, a back section embraced by the extended portions of said flexible element, covers having attaching portions arranged on opposite sides of said back section, and fastening devices extending through said attaching portions and said back section and securely engaging said ettaching portions With said back section.

5. A book comprising leaves, a flexible element secured to the leaves and extending beyond opposite sides of the same, and a back section embraced by the extended portions of said flexible element, the leaf-contacting side of said back section. being curved transversely.
